GASKET CUTTER.

1 Application filed August `1*?, 1921. Serial No. 492,926.

To @Zlio/m t may concern.'

Be it known thatr l', Crmnnns H., Harn Niivss, a citizen of the Republic of Chile,v and a resident of the city oi Chicago, in

the- .county of Cook and State of lllinois, have invented certain new and useiul'lmprovements in a Gasket, Cutter; vand l do hereby declare that the following is a full, clear, and exact description of the same,

reference being had to thev accompanying drawings, andy to the numerals of reference marked thereon, which form a part of this specification.

This invention relates to' a gasket cutter, and particularly to' a device .which is adapted to be` used to cut properly 'formed gaskets,v washers and .similararticles Airom sheets of suitable material with a single operation.A ,i

a cutting device of the class described which will cut the articleto the proper torni andautomatically eject the saine after it iscut from a sheet oi stock material.

It is a further object of this invention to provide a gasket-cutting device having a spring-impelled ejector.

It is an important object of this invention to provide an improved cutter ldevice of the `classfdesc-ribed having an adjustable automatic ejector mechanism, and being adapted.

shown on the drawings and 'hereinafter' more fully described.

On the drawings: v Figure 1 is a central vertical section with parts in' elevation showing a gasket cutting device embodying the principles of this" invention.

Figure 2 is a bottom plan View of the device.

Figure 3 is a section on the line 3 3 of Figure 1. i

Figure 4 is a section on the linea-410i Figure 1.

Figure 5 is a section on the line 5-5 of Figure 4.

Figure 6 is a view similar to Figure 1, showing a device embodying a single cutter.

t is an yobject oi'this invention to provide Figure 7 isa bottom plan view of the device shown in Figure 6. i

As shown on the drawings:l i

The cutter device of this invention is provided ;with a handle 1, and integrally formed on or otherwisel securedtoy one end of said handle isa cylindrical cutter portion cylindrical portion extends outwardly there# from and abuts the end .of said handle. f Integralliy formed on said flange 5 and eX- tendingy axially inside the cutter 2 vis an inner cylindrical cutter'member ,6, Awhich is separated romthe inner side of the cut. ter 2 by a distance equal to thewidth of the gasket or washer required. Slidably mountedvv inside the cylindrical member 4 andv eX- tending axially through the cutter 6 vis *aV rod 7 which has a plunger member 8- formed on ,its lower end, said plunger or ejector member 8 being slidabl'e in the lower end of the cutter member@ 'and' being .adapted to eject cut out material from the `stock sheets and irom said cutter.y 1 i Said plunger 8 is connected with an annu-` laryplunger or ejector member 9, which is -slidable between the lower ends of the cutters Quand 6, `by `mea-:ns oi'i va transverse rod 10, which extends through the plunger 8l and outwardly: through slots 11 in the cutter 6 into saidl plunger 9. The ,ejector plungers 8 and 9 are resiliently held downwardly in position adjacent they cutting edges of the cutters 2 and 6 by meansl of a helical s ring. 12 which is enOaOed between P L, 23 b they upper side of the plunger 8 and the langedzend-,of an adjusting collar 13 which` is engaged around therod`7 and which mayV beadjusted vertically in a threaded recess 14 formed in the cylindrical member 4. Slots or-notches 15 formed in the flange on kthe adjustingcollar 13 afford means whereby the sameV may be engaged by a suitable tool and rotated for eccentric adjustment in the recess 14C.v `Therelat-ive vertical movement of the'ejector plunger-s 8 and 9 and of the rodl 7 is limited by a stop 16 which is formedon the inner. end of a set screw 17 extendingthrough the handle 1 and the cylindrical memberg't into a longitudinal lil said rod l therein.

Figures 6 and 7 illustrate a single gasket cutter which is constructed according to the principles of this invention and which is particularly used for cutting` washers, small disks and the like. ln this construction the inner cutter 6 is omitted, and the plungers 8 and 9 are replaced by a plunger 20 which is formed on the lower` end of the rod 7 and which extends outwardly through the inner wall of the cutter 2. rllhe device is conveniently assembled by properly positioning the inner cutter 6 and the ejector mechanism which is supported thereon and inserting this inner cutting mechanism into said recess in the handle l, after which the set screw 17 may be. inserted, the mechanism being so positioned that the stop 16 on said set screw is engaged in the slot 18 in the upper end of the rod 7. it the time when this assembly is effected, and before the rod 7 is moved into position, the adjusting collar 13 should be adjusted to the proper vertical position to maintain the desired amount of compression on the helical spring 12, and in case that the spring l2 becomes weakened, said adjacent a longitudinal recess 19 adjusting collar may of course be again ad-A justed to increase the compression thereof.

The device is used in much the same manner as the ordinary hand punch, and after the 'cutting blow is struck, the finished washer or gasket is automatically1 ejected from the device by the action of the spring on the plungers 8 .and 9 or on the plunger 20. rlhe device is particularly adapted for and will operate satisfactorily in the cutting of gasket composition material, rubber, cork, fibrous material, lead, and a variety of other materials which need not be enumerated. @n account of the few simple and strong parts, there is little likelihood of the device getting out of order, and the provision of the improved ejector mechanism greatly facilitates the cutting of the gaskets, washers and the like from sheets of stock material.

l am aware that numerous details of construction maybe varied .through a wide range without departing` from the rprin-j ciples of this invention, and l therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.

l claim as my invention:

l. A devicev of the class described comprising a handle member, a cutter thereon, a second cutter coaxial with the first cutter and supported by the handle member, a rod slidably mounted in the second cutter, ran ejector-plunger on the rod slidable in the end of said second cutter, a 'second ejectorplunger slidable between the first and second cutters and connected to saidy first mentioned ejector-plunger for movement there with, and a helical spring inside the secondl cutter for normally forcing said plungers outwardly.

2. A. device of the class described comprising av handle member, a cutter thereon, a second cutter coaxial with the first cutter and supported by the handle, an ejectorplunger slidable in the end of the first cutter, second ejector-plunger slidable between the first and second cutters and connected to said rst mentioned ejector plunger for movement therewith, a spring for normally forcing said plunger' outwardly, and a stop for limiting the movement of the plunger-s relative to the cutters.

3. A device of the class described comprising a handle member, a cutter thereon, a second cuttercoaXial with the first cutter and supported bythe handle member, a rod slidably mounted in the second cutter, an ejector-plunger on the rod slidable in the end of the first cutter, a second ejectorplunger slidable between the first and second cutters and connected to said first mentioned ejector-plunger for movement therewith, a helical spring for normally forcing said plungers outwardly, and means for varying the compression on said helical spring.

t. A device of the class described comprising a handle member, a cutter thereon, a second cut-ter coaxial with the first cutter and supported by the handle, a rod slidably mounted in the second cutter, an ejector' plunger on the rod slidable in the end of the first cutter, a second ejector-plunger slidable between the first and second plungers and connected to the first mentioned ejectorplunger for movement therewith, ahelical spring inside the second cutter for normally forcing said plungers outwardly, and a vertically adjustable member inside the second cutter for varying the compression lon the spring.

5. A device of the class described coin-p prising a handle member, a cutter thereon, a second cutter coaxial with the first cutter and supported by the handle, a rod slidably mounted `in the second cutter, an ejectorplunger on the rod slidable in the end of the first cutter, a second ejector plunger slidable between the first and second cutters, and resilient means for normally forcing said plungers outwardly.

6. rlhe combination with a gasket cutter, of ejector means operable therein, a spring actuating means for said ejector means, and means for adjusting the action of said actuating means. l
